  • Focus on Your Business, Not Your Hammer

    You don’t need to be a hammer expert as our expertise is on call for you. Built-in features like automatic shut-off protect your equipment from poor operation techniques or the occasional mistake. Internal buffering and integral silencing keeps the noise and power on the job, and out of the cab. If you can run an excavator, you can run a Cat hammer like a pro.

    Easy to Operate

  • Auto shut off prevents blank firing, the leading cause of user-induced damage to hammers.
  • On a Next Gen Cat Excavator, hammers are protected by Auto-Stop, preventing damage from over-hammering in a single spot.
  • This feature helps prevent damage to your machine and premature damage to your hammer, even with inexperienced operators
  • Performance Hammers lead in both operator comfort and machine protection.
  • The buffering system qualitatively dampens vibration to the machine due to proprietary buffering material.
  • Can be configured for joystick or foot pedal control to suit your operating preference.
  • Spend Less Time on Maintenance

    Daily greasing is a snap, with one basic point at a convenient height. With the addition of a Cat autolube, the hammer is greased while it runs
     - not just saving you time, but protecting your investment. Rotate or change the bushing in less than an hour. Gas checks are annual, and quickly accomplished without dismounting the hammer. You can do this yourself… or your Cat dealer can provide comprehensive support on your schedule.

    Next Level Technology

    • All models include Product Link technology standard, you can locate the hammer via the Cat App on your phone.
